Wood Forget-me-not

It is a short-lived herbaceous perennial plant, growing to 12–30 cm (5–12 in) tall by 15 cm (6 in) wide, with hairy leaves and a profusion of flowers with petals longer than their tube, pink in bud then opening disc-shaped, intensely sky-blue with yellow centres in spring. Stace (2011) describes this plant as having the following characteristics:

Upright, to 50 cm; softly hairy, with hairs at more-or-less right-angles to the main stem. Flowers sky-blue, to 6–10 mm across, flat in profile; sepal tube with hooked hairs; April–July. Mature fruit dark brown, shiny. Mature calyx on spreading stalks longer than sepal tube; calyx teeth spreading to expose the ripe fruit. Basal leaves stalked, in a rosette; upper leaves not stalked. Generally found in woods, scree and rock ledges; common throughout the British Isles.

Widely cultivated throughout the temperate world, it is particularly associated with spring bedding schemes involving other spring-flowering subjects, notably daffodils, tulips, wallflowers, and primulas. Typically seeds are sown one year to flower the next. Though short-lived, plants readily self-seed in favourable situations. Plants maintain leaf growth throughout winter. M. sylvatica is also a parent of numerous cultivars in shades of pink, blue and white. The cultivars 'Bluesylva' and the compact 'Blue Ball' have gained the Royal Horticultural Society's Award of Garden Merit. Other cultivars include:

'Blue Basket', a taller variety with deeper blue flowers 'Music', erect and large flowered 'Pompadour', compact, ball-shaped with large rose-pink flowers 'Snowball', white flowers 'Ultramarine', dwarf with very deep blue flowers 'Victoria Rose', bright pink flowers
